Added an 'AllowSHMPixmaps' X configuration option, which can be used to prevent applications from using shared memory pixmaps; the latter may cause some optimizations in the NVIDIA X driver to be disabled.

Resolved various stability problems on GeForce 8, 9 and GTX GPUs, as well as some GeForce 6 and 7 PCI-E GPUs.

Fixed a bug that resulted in GPU errors when changing the TwinView display configuration while using Compiz.

Further improved the error recovery paths taken in case of GPU command stream corruption.

Removed an old workaround that caused incorrect fake Xinerama information to be reported after enabling a second TwinView display.

Fixed the subpicture component order reported by the NVIDIA X driver's XvMC implementation.

Fixed a problem that could result in IRQs being disabled on some multi-GPU SMP configurations.

Worked around cache flushing problems (on some Linux kernels) that caused corruption and stability problems.

Added experimental support for PCI-E MSI.

Improved compatibility with recent Linux 2.6 kernels.
